You may also notice the offer, at right, for a special pair of glasses glasses. Order them—or, if you have them already, remove them from their plastic casing and put them on; you will notice that when viewed through these glasses, the doubly printed words appear to leapleap off the screen screen.

At first, the effect may be disorienting, so we recommend that you enter this brave new world slowly. Compare these two simple sentences:

He lunged lunged at her with the icepick icepick.

Thrilling, huh? From this moment on, nothing will ever be the same. Pieces on this site—a few at first, and then more and more—will be printed using 3*TYPE. Characters and scenes that were static upon the page will now extend into your living room. It may be hard to imagine how exciting this will be, just as it would have been difficult for a caveman to imagine an iPod or a microwave oven.
